Martin Storsjö 93bf4a74de configure: Fix enabling memalign_hack automatically 
simd_align_16 is a configure item that can be enabled or disabled,
it's not a variable containing a list of other configure items
as need_memalign previously. This was broken in eba2233b5.

Martin Storsjö 5276174859 lavc: Move the libtwolame encoder registration to the list for external libraries 
This makes sure the default behaviour of using the internal encoder
stays the same regardless if libtwolame is enabled or not (as for
any external library).

This fixes fate-lavf-mpg if libav is built with libtwolame enabled.

only happen if avctx->height <= 0, which is validated elsewhere. Doesn't hurt
to still initialize it though.

Vittorio Giovara bae05e5326 matroskaenc: write correct Display{Width, Height} in stereo encoding 
should be the raw amount of pixels (for example 3840x1080 for full HD side by
side) and the DisplayWidth/Height in pixels should be the amount of pixels for
one plane (1920x1080 for that full HD stream)."

So, move the aspect ratio check in the mkv_write_stereo_mode() function
and always write the embl when stereo format and/or aspect ration is set.
Also add a few comments to that function.
